IMPROVEMENT IN SHAFTS FORQVEHICLES.

Specification forming part of Letters Patent No. 209,540, dated November5, 1878; application filed August 23, 1878.

To all whom it may concern: Be it known that I, JoHN Q. ADAMS, of RoyalOak, in the county of Oakland and State of Michigan, have inventedcertain new and useful Improvements in Combined Shafts and Gross-Bar forVehicles; and I do hereby declare that the following is a full, clear,and exact description thereof, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification.

Figure 1 is a view of the blank before bending, and Fig. 2 is a view ofthe combined shafts and cross-bar after bending.

This invention relates to certain improvements in combined shafts andcross-bar for vehicles; and it consists of a pair of shafts and across-bar constructed from one piece, as hereinafter fully described,and particularly pointed out in the claim.

In the accompanying drawings similar letters of reference indicatecorresponding parts in the figures.

The blank A may be dressed as nearly as possible to the required shape(the outline of which is shown in Fig. 1) before the notch a and gainsor slots 1) b are cut therein, thus forming stubs c c, the ends of whichface each other at the notch a, which is at the center of the blank. Itshould be then steamed and bent to the shape shown in Fig. 2, anddressed to the required shape. Bolts B are then inserted at what may betermed the junction of the shafts and the cross-barG, to strengthenthem, and the ordinary ironing may be proceeded with.

-I t will be seen therefore that the shafts D and the cross-bar G areconstructed of one piece of timber, requiringno mortises or tenons, andhaving the grain of the wood running in lines and curves that impart tothe device the greatest amount of natural strength.

Having thus described my invention, what I claim as new and useful, anddesire to secure by Letters Patent of the United States, is

The combined shafts and cross-bar formed of the blank A, and providedwith the bolts B B, substantially as and for the purpose herein setforth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

JOHN o. ADAMS.
